Cell C rude agents, I competent agents

My contract is said to end by the end of March 2024. I went to the store in game city since they have been trying to make me take on another contract. I adviced them that I will not be taking anything, I wanted to give them notice of the ending of my ending contract. I was told to call the their department, I was given a number to call on the 21st of March 2024. I then called and pressed the appropriate option and I was then transferred by several agents and the option to end my contract was not available, try again later. Tried several times till I took an option to take a contract, found an agent by the name of Nokuphila, she refused to give me her surname, asked for her supervisor, she told me to wait for 2mins while she spoke to her supervisor. She then came back told me that the supervisor was in a meeting can't be with me, he can only call me later. I refused to take that, I then asked for the supervisors details she refused. Then she dropped my call, I phone back severals times, I still did not meet any help. Cell C please I want to see justice being done. If this is the way you handle your customers.
